Chapter 1 Overview

The Synway TEJ400P, TEJ400E, TEJ800P, TEJ800E, TEJ401P, TEJ401E, TEJ801P and TEJ801E are digital trunk interface boards which support E1, T1 and J1 in Asterisk. As the second generation of the Synway TEJ series, they are in 2U size, 120mm in length, compact in structure and high in integration. Among them, TEJ400P, TEJ401P, TEJ800P and TEJ801P include 3.3V PCI bus, while TEJ400E, TEJ401E, TEJ800E and TEJ801E include PCIex1 bus, designed especially for various application systems that require high performance.

They all perform echo cancellation by on-board DSPs. The enhanced capability of TEJ401P, TEJ401E, TEJ801P, TEJ801E in echo cancellation reaches 128ms for time delay estimation, which ensures high-quality voice talk without extra modules or devices to support echo cancellation. They are absolutely cost-effective. The design of on-board EMC and lightning-proof circuits further guarantees the security in use.

These boards are completely compatible with Asterisk in hardware and support smooth connection to Asterisk platform. Therefore they have a lot of advanced call features.

Supported Data Modes: Cisco HDLC, HDLC, PPP, Multi-link PPP, Frame Relay. Supported Voice Modes:

PRI CPE and PRI NET — NI1 — NI2 — EuroISDN — 4ESS(AT&T) — 5ESS(Lucent) — DMS100

E&M — Wink — Feature Group B — Feature Group D

FXO and FXS — Ground Start — Loop Start — Loop Start with Disconnect Detect

These boards connect the Asterisk server with PSTN, Channel Bank or PBX via T1, E1 or J1 interface to build a specialized telephony network environment. Figure 1-1 and Figure 1-2 below are typical application models with these boards.

1.1 Features

PCI/PCIe Bus Support

TEJ400P/TEJ401P/TEJ800P/TEJ801P includes PCI bus, PCI r2.2 compliant; in the universal PCI design, it supports 3.3V/5V PCI slot and PCI-X slot.

TEJ400E/TEJ401E/TEJ800E/TEJ801E includes PCIe bus, PCI Express r1.0a compliant; supports PCI Express X1, X4, X8, X16 slots and the PNP (plug and play) feature.

DMA Read and Write

The use of DMA technique for data reading and writing helps minimize the cost of the host CPU.

Compatible with Asterisk

Entirely compatible with Asterisk in hardware, with all source codes open.

RJ48C Jack

The TEJ400P, TEJ400E, TEJ800P, TEJ800E, TEJ401P, TEJ401E, TEJ801P, TEJ801E boards all have four RJ48C jacks. Among them, TEJ400P, TEJ400E, TEJ401P and TEJ401E have common RJ48C jacks which can either connect directly with digital trunks or convert to BNC connectors via a proper adapter, while TEJ800P, TEJ800E, TEJ801P and TEJ801E have special RJ48C jacks (RJ48C/M) each of which can convert to two common

Echo Cancellation

The echo cancellers that Synway developed for these boards use on-board DSPs to work. TEJ401P, TEJ401E, TEJ801P and TEJ801E support up to 128ms for time delay estimation per channel, while TEJ400P, TEJ400E, TEJ800P and TEJ800E support 32ms, really cost-effective. It not only cancels out the effect of voice playback on DTMF and busy tones detection, but also avoids self-excited oscillation and howling, and minimizes the possibility of registering wrong DTMF and busy tones in a conference call, designed especially for VoIP application environments.

Voice CODEC Support

Supports A-law, μ-law codecs.

Clock Sync Support

Supports input and output of CT clock, allowing clock synchronization with multiple boards.

2.5 Hardware Installation

Note: Always turn off the power before installation!

Step 1: Configure the grounding jumper.

To use 100ΩT1, 110ΩJ1 or 120ΩE1 balanced twisted-pair cable, disconnect all grounding jumpers.

In consideration of various line conditions, this series boards are equipped with two groups of grounding jumpers on each channel which respectively control the groundings of the transmitting and receiving ends. In case the 75ΩE1 unbalanced coaxial cable is used, the grounding jumpers at the receiving end should be disconnected while those at the transmitting end should be short-circuited, provided that the PC is properly grounded. This configuration is the factory default setting and applicable to most situations so that there is usually no need to change it. If it is difficult to ground the local PC, you may short-circuit the on-board grounding jumper at the receiving end and use the transmitting end at the opposite terminal for grounding. If the receiving end at the opposite terminal is grounded (improper operation), the on-board grounding jumper at the transmitting end must be disconnected. Refer to Table 2-3 for details.



Generally speaking, even in the case of proper grounding at both terminals, only the external layer of the E1 coaxial cable at the transmitting end is allowed to be grounded. The grounding of both transmitting and receiving ends may result in a current loop with ground wires, bringing instability to signals. Therefore, such grounding must be strictly avoided.

Step 2: Properly fit the board onto the PC chassis.

It is suggested to fix the L-brackets on the board with screws before going to the next step.

Step 3: Connect to digital trunks.

A TEJ800P, TEJ801P, TEJ800E or TEJ801E board provides 4 RJ48C/M jacks, each of which in use should be converted to 2 common RJ48C jacks via a two-way hub as shown in Figure 2-6 below. Each common RJ48C can either connect directly with digital trunks or convert to 2 BNC connectors via an RJ48C-to-BNC adapter. See Figure 2-7.

Figure 2-6 Two-way Hub for RJ48C/M



Figure 2-7 RJ48C-to-BNC Adapter

A TEJ400P, TEJ401P, TEJ400E or TEJ401E board provides 4 common RJ48C jacks, each of which can either connect directly with digital trunks or convert to 2 BNC connectors via an RJ48C-to-BNC adapter. See Figure 2-7 above.

Step 4: Set up an application environment.

Connect digital trunks with the on-board RJ48C jack to establish an application environment.

Step 5: Connect the clock sync line.

Note: Skip this step if there is no need of clock synchronization with multiple boards.

The on-board clock sync line is used to connect with other boards, such as digital trunk boards, analog boards from Synway or even boards from other companies, to offer a same clock to all boards connected together. This can reduce the error in faxing and guarantee the accuracy in data transmission between boards.

See Figure 2-8 below for the clock sync line provided by Synway.

Figure 2-8 Clock Sync Line

Step 6: Boot your computer and install the driver.

Regarding driver installation, refer to the file ‘SynAST UserManual.doc’ for details.
